Bittorrent is not a threat to the very source of the power of the economic elites of the world. Currency creation and manipulation is. So expect a 1 million times stronger reaction to something that puts their power in danger.

"Banking was conceived in iniquity and was born in sin. The Bankers own the earth. Take it away from them, but leave them the power to create deposits (money out of thin air), and with the flick of the pen they will create enough deposits to buy it back again. However, take it away from them, and all the great fortunes like mine will disappear and they ought to disappear, for this would be a happier and better world to live in. But, if you wish to remain the slaves of Bankers and pay the cost of your own slavery, let them continue to create deposits (money out of thin air)." — SIR JOSIAH STAMP, (President of the Bank of England in the 1920's, the second richest man in Britain)

I really doubt the government of major countries like the US, the UK, Germany, France, or other european countries would ban bitcoin, plus it would be hard without blocking ALL peers outside of their country, and that would pretty much make the government hated and destroy their internet, so I doubt they would.
